The resident app is the primary surface through which a resident encounters the operating layer. Its design follows a single principle: residents should not experience the system, they should experience the building. Every workflow the building offers — entering a space, booking an amenity, reporting an issue, receiving a delivery, paying rent — is one place, with consistent rules, reliable confirmations, and a single source of truth.

The app is offered as a white-labeled native experience and as a progressive web surface for residents who do not install apps. Brand customization spans typography, color, copy, and the building's identity — but the structural elements of the experience, the workflows, and the response times are governed by the behavioral standard. The app cannot be themed in a way that violates the specification.

Offline behavior matters. The app maintains a cached representation of the resident's permissions, recent bookings, and active issues. During cloud connectivity loss, access decisions and amenity check-ins continue through the edge gateway; the app shows a clear offline indicator and reconciles state when the link returns. Residents should never see a blank screen because a cloud service is degraded.
